XMLParseException during dynamic theme generation

Question

Hi,
I4m having problems with SQL statements in some requests to MapViewer during dynamic theme generation.
When I put in the WHERE clause the operator "less than" the request fails. An XMLParseException is generated.
For example:
<jdbc_query XXXXXXX>
select geom from table where column < 10
</jdbc_query>
the following exception is generated:
oracle.xml.parser.v2.XMLParseException: Expected name instead of .
When I change de symbol < to &lt; (like MapViewer Users Guide recommends):
<jdbc_query XXXXXXX>
select geom from table where column &lt; 10
</jdbc_query>
the following exception is generated:
oracle.xml.parser.v2.XMLParseException: Unexpected EOF
If the is no WHERE clause (select geom from table) the request works.
What can be wrong ? Can I use the less than operator in the WHERE clause ?
Thanks in advance,
Rodrigo     

Answer 1

OK. The OC4J version is 1.0.2.2.1. I4m using Oracle8i Enterprise Edition Release 8.1.7.0.0.
Some examples of XML requests:
1) This works fine
<?xml version="1.0" standalone="yes"?>
<map_request
title=""
basemap="MAP1"
datasource="DS1"
width="1098"
height="648"
bgcolor="#FFFFFF"
antialiase="false"
format="GIF_URL">
<center size="73063.00272634998">
<geoFeature>
<geometricProperty typeName="center">
<Point>
<coordinates> 376875.541941716, 7810266.276712325</coordinates>
</Point>
</geometricProperty>
</geoFeature>
</center>
<themes>
<theme name ="PLANTIOS_MPD">
               <jdbc_query
               asis="true"
spatial_column="GEOM"
               render_style="C.PLANTIOS_MPD"
               jdbc_host="MyServer"
               jdbc_port="1521"
               jdbc_sid="db01"
               jdbc_user="scott"
               jdbc_password="tiger"
               jdbc_mode="thin">
               select geom from table where column = 50
</jdbc_query>
     </theme>
</themes>
</map_request>
2) This doesn4t work ('<' replaces '=' in SQL WHERE clause)
<?xml version="1.0" standalone="yes"?>
<map_request
title=""
basemap="MAP1"
datasource="DS1"
width="1098"
height="648"
bgcolor="#FFFFFF"
antialiase="false"
format="GIF_URL">
<center size="73063.00272634998">
<geoFeature>
<geometricProperty typeName="center">
<Point>
<coordinates> 376875.541941716, 7810266.276712325</coordinates>
</Point>
</geometricProperty>
</geoFeature>
</center>
<themes>
<theme name ="PLANTIOS_MPD">
               <jdbc_query
               asis="true"
spatial_column="GEOM"
               render_style="C.PLANTIOS_MPD"
               jdbc_host="MyServer"
               jdbc_port="1521"
               jdbc_sid="db01"
               jdbc_user="scott"
               jdbc_password="tiger"
               jdbc_mode="thin">
               select geom from table where column < 50
</jdbc_query>
     </theme>
</themes>
</map_request>
3) This also doesn4t work ('&lt;' replaces '=' in SQL WHERE clause)
<?xml version="1.0" standalone="yes"?>
<map_request
title=""
basemap="MAP1"
datasource="DS1"
width="1098"
height="648"
bgcolor="#FFFFFF"
antialiase="false"
format="GIF_URL">
<center size="73063.00272634998">

<geometricProperty typeName="center">

<coordinates> 376875.541941716, 7810266.276712325</coordinates>
</Point>
</geometricProperty>
</geoFeature>
</center>
<themes>
<theme name ="PLANTIOS_MPD">
               <jdbc_query
               asis="true"
spatial_column="GEOM"
               render_style="C.PLANTIOS_MPD"
               jdbc_host="MyServer"
               jdbc_port="1521"
               jdbc_sid="db01"
               jdbc_user="scott"
               jdbc_password="tiger"
               jdbc_mode="thin">
               select geom from table where column &lt; 50
</jdbc_query>
     </theme>
</themes>
</map_request>
Thanks,
